Abstract

The invention relates to a method for the treatment of bath water / splash water from a bath (1) in a circuit, wherein the splash water is collected, then filtered in a non-pressurized filter system and after disinfection and pH regulation as pure water the bath (1) is returned. The splash water is collected directly in an intermediate container (3) and stowed in this to a level (3a), from which it is passed by pressure difference in the non-pressurized filter system, wherein the water level (3a) allows an excess of surge water, which overflows separately is collected and optionally or as needed on the filter system (9) and / or in the intermediate container (3) is pumped.

Description

The The invention relates to a method for the treatment of bath water / splash water from a bath in a cycle, where the splash is collected, then is filtered without pressure and after disinfection and pH regulation is returned as pure water to the bath. The invention further relates to a device for processing of bath water / splash water from a pool in a water cycle, which at least one container for Collecting the splash water, a non-pressurized filter system and pumps contains.

at one of the known methods for bathing water treatment is the overflowing in an overflow channel Pool water or splash water collected in a container and out of this by means of at least one transfer pump of a non-pressure working Filter system supplied. The unfiltered water is added to a flocculant, which is dirt binds, so that they can be easily filtered off. The Filter system comprises one or more closed, non-pressurized filters, as a filter material, for example, sand or a multi-layer filter material contain. The filtrate water is disinfected, usually by chlorination, and subsequently after pH regulation over an inflow system returned to the bath. In front The chlorination can be a partial flow of water for heating a heat exchanger be directed. In such a system usually operates at least a transfer pump, in particular for conveying the water from the collecting container in the Filter chambers. To carry the filtrate water to the pool pressure booster pumps are used. Promotes in known systems the transfer pump the entire volume of water from the surge tank on the filter system.

Of the Invention is based on the object, in a method of the above mentioned type and in a device of the type mentioned in a structurally simple and cost effective way in the water cycle required pump power and thus the required electrical energy significantly to reduce.

The inventive method solve the asked Task in that the splash water collected directly in an intermediate container and is jammed to a level of which it is due to pressure difference is passed into the filter system, the stagnation level is a surplus allows for splash water, which overflows and is collected separately and optionally or as needed on the Filter system and / or is pumped into the intermediate container.

According to the device according to the invention is solved this task by that an intermediate container is provided for the direct absorption of the surge water, which is connected to the filter system, wherein in the intermediate container of the higher Pressure prevails and an overflow to the constant Flow away a proportion of accumulating splash water provided in a surge tank is.

By the pressure difference between the dammed water and the Water in the filter passes the surge water passively - without pump support - directly into the filter. A certain amount of splash water is considered overflowing Water collected separately and continuously, as needed, in Filter pumped. This ensures that the different costs arise Schwallwassermengen can be compensated. Many bathers go to Water is the proportion of overflowing water because of the higher displacement bigger in the short term, leave bathers the water, it must be ensured that sufficient from a reservoir Water can be pumped into the filter system.

At the inventive method it is essential to supply the filter system with water guarantee. It is therefore envisaged that the surge water surplus by means of an overflow in a surge tank flows, from which the collected water by means of a transfer pump is sucked off, whose power to the water level in the filter system is adjusted, preferably electronically regulated accordingly becomes.

is the intermediate container structurally in the expansion tank Integrated, a compact design of the entire system is supported.

Further Features, advantages and details of the invention will be apparent from the schematic drawing illustrating two embodiments described in more detail. The two drawing figures each show a schematic of an embodiment a system for the treatment of bath water.

Both drawing figures show a bath 1 , which is filled with bath water and its collected in an overflow torrent over at least one surge water pipe 2 in an intermediate container 3 passed and in the container 3 to a level 3a , from which an overflow takes place, is stowed. To filter the pool water is a filter system 9 provided with one or more non-pressure filters. The variants shown each have a filter 9 shown. The water column in the filter 9 is lower than that of the intermediate tank 3 dammed up water. Due to the pressure difference thus given flows over the provided line 8th Splash water from the intermediate tank 3 in the filter chamber 9b of the filter 9 , Before entering the filter chamber 9b is the splash water through a metering device 15 a flocculant added. In the execution according to 1 is at the bottom of the intermediate container 3 a process 18 connected, which closed during normal operation of the system and for emptying the intermediate container 3 is opened. An emptying, for example, be required if a cleaning of the overflow channel of the bath 1 is carried out. One at the bottom of the intermediate container 3 provided revision opening 14 allows removal of any registered larger items, wherein before opening the inspection opening 14 the intermediate container 3 is also emptied.

The filtered water comes with a circulation pump 12 via a filtrate line 11 from the filter chamber 9 and in a pure water line 13 the bathing pool 1 recycled. The in the pure water line 13 transported water can be added at appropriate locations on dosing means not shown, means for adjusting the pH and disinfectant.

Another essential component of the system is an expansion tank 5 in which the from the intermediate container 3 overflowing splash water is collected, as in the two figures by the overflow pipe 4 is indicated. The himself in the expansion tank 5 collecting fraction of the accumulating surge water is by means of a transfer pump 6 to the filter chamber 9b promoted and / or the intermediate container 3 returned, as in the figures by lines 7 . 7 ' is indicated. The expansion tank 5 thus serves to equalize the accumulating in different amounts bathing in the bathing activity. As is known, the proportion of displacement water in the surge water can fluctuate greatly. In an intensive bathing operation, for example, if the proportion of displacement water is relatively high by persons jumping into the water, also increases the amount of effluent water. The different accumulating amount of splash water is through the expansion tank 5 compensated. It is beneficial to the performance of the pump 6 to the water level in the filter system by providing an electronic control of the pump capacity 6 In each case, to ensure that the filter system does not run dry. At the appropriate locations, therefore, a measurement and recording of actual values must take place via sensors or other devices.

A replenishment of fresh water in the bath 1 takes place depending on the water level in the expansion tank 5 ,

The exhaust air from the containers 3 and 5 is about venting 19a . 19b dissipated.

A particular advantage of the system according to the invention and of the method according to the invention is the achievable energy saving over conventional systems. After a large part of the splash water passively into the filter system 9 can be omitted in larger plants in the order of about 80% of the usual in the treatment circuit pumping services.

2 shows a variant of in 1 presented plant, which differ from that according to 1 it differs in that the intermediate container 3 inside the expansion tank 5 is positioned or integrated in this. It is therefore the process 18 for emptying at the bottom of the expansion tank 5 intended.
